Hi there!
Last year I was doing year 12 and got BMO Round 2 certificate of merit and won some Ukrainian math olympiads. This year I applied to Oxford for CS and was rejected. Additionally, I messed up my a-levels with A*AB(maths, physics, further maths).
Now I am taking a gap year and have several choices
1. Retake a-levels(should I retake all or just further maths?) and apply for Cambridge or Oxford maths or physics/engineering
2. Retake and try law
What can you recommend? Also I checked acceptance rates and it is higher for Cambridge maths rather than Oxford so i think i should apply there
